It's the same as the suicide or powerlyte shells. You have to knock the pin out with something. I used a hammer and punch and pressed it the rest of the way out with a safety pin but I'm sure you can figure out something if you don't have those. I've never owned a warrior so I don't know if they have the * on 1 side of the pin or if it's just a straight pin so look for it and make sure your knocking it out the correct side
